The founder of modern Saudi Arabia, Abd al-Aziz, captured Riyadh at the turn of the 20th century, and began his efforts to unify the many factions on the Arabian Peninsula.
It took many decades but he enjoyed a large measure of success.
Saudi Arabia (to its credit) still uses much of the profits from that industry to improve the infrastructure of the country and the lives of its people.
Although there is evidence of human existence in Saudi Arabia dating back 20,000 years, the harsh climate prevented any permanent settling, and it wasn't until the Ottomans expanded their empire in the 16th century that any major developments occurred.
In 1744, the first Saudi state was created near the region of Riyadh.
